To all whom it may concern Be it known that I, WILLIAM H. PARK, acitizen of the United States, and a resident of New York, in the countyof New York and State of New York, have invented certain new and usefulImprovements in Serum-Containers, of which the following is aspecification.

This invention relates to containers for serums and similar materialsintended to be administered by means of hypodermic injections, and itsnovelty consists in the construction and adaptation of the parts as willbe hereinafter more fully pointed out.

In practice serums must be sterilized and preserved out of contact Withthe air in order that they may not become infected with foreign bacilliand thus introduce in the system of the patient for whose use they areintended complications which might. be disastrous to his health or life.At the same time such .serums must be preserved in a container in whichthe hypodermic needle can be promptly and securely inserted, and aftersuch insertion must be administered by compression so as to force theserum through the needle without any contact arising with any substanceapt to contaminate the serum. In order to meet these requirements I haveinvented the container which is the subject matter of this applicationfor Letters Patent. It is so made that the serum contained therein doesnot affect any of the materials of which it is composed and is notaffected by them. It is readily adapted to the use of hypodermic needlesof different sizes, which needles can be readily inserted in theordinary closure of the container, and it is provided with means foradministering the serum after the insertion of the needle without theuse of any additional or supplemental device.

In the drawings Figure 1 is a central lon-- gitudinal section of adevice embodying my invention. Fig. 2 is a section of the stopper andtemporary closure, and Fig. 3 is a detail of the needle employed withthe container.

In the drawings 10 is a tubular body of glass or similar materialneutral with respect to the serum to be contained therein. It isprovided with a restricted neck indicated at 11 and with an open flaringbottom having an outwardly extending annular fiangel-EZ. The tubularbody is of approximately the same internal diameter throughout and isadapted to contain a retainer 13 of cork, paper, compressed pulp orsimi- 'lar inert material and a plunger 14 having an elastic or softhead made to fit tightly inside of the tubular body and adapted to serveas an air compressing piston when reciprocated therein.

Inside of the neck is a stopper preferably made of rubber or similarelastic inert material and comprising a tubular body 20 adapted to andalso if desired provided with an external annular flange 21. It is alsoprovided with an aperture 22 extending the entire length of stop-per.

30 is a temporary closure adapted to fit inside of the aperture 22. Itis preferably made globular in shape and of inert material which willnot oxidize or become affected by the serum or which in turn will notafi'ect the serum injuriously. I have found that glass is a goodmaterial for the purpose indicated.

hypodermic needle is shown at 4:0. It is provided'with the usual centralaperture and with a projecting annular flange 41.

In using the device, the tubular body 10 is first sterilized preferablyby heat, and the retainer 13 also sterilized is inserted within itpreferably near enough to the neck 11 so that a suitable quantity of theserum may be placed between the retainer and the stopper 20 after thelatter is inserted. The plunger It with its elastic head is theninserted within the tube 10. The serum is'then introduced and thestopper 20 with the aperture 22 in which the temporary stopper 30 hasalready been inserted is sterilized and put in place. The serum is thusprotected from contact with the outer air and from any infectingsubstances-carried thereby.

When the instrument is to be used the shank of the needle 40 is insertedin the aperture 22 of the stopperand the temporary stopper 30 is pushedout of such aperture and inside of the tubular body. The plunger 14: ispushed forward and this in turn moves the retainer 13 which also movingforward forces the serum through the hollow body of the needle 40.

at I claim as new is: 1. A stopper for a device of the characterdescribed provided with a needle receiving t tightly within the neck 11aperture extending therethrough and a temporary closing device therein,the stopper being made of elastic material and the temporary closingdevice being made of rigid material unafi'ected by serum, substantiallyas described.

2. In a device of the character described, the combination of a stopper,said stopper provided with a needle receiving aperture provided with anaperture extending therethrough, a temporary closing device of greaternormal diameter than the said aperture located therein and adapted to beforced bodily out of said aperture by the shank of a needle when passedtherethrough, the materials of the said temporary closing device and theportion of the stopper surrounding the aperture being such that thestopper is held in said aperture by pressure due to the compression ofsuch materials, and the material of said closing device being unaffectedby and having no deleterious effect upon serum.

Witness my hand this 23d day of November, 1911, at the city of New York,in the county and State of New York.
